Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are working adults aged 40–62 at risk for lung cancer or TB with a registered Zalo account and no contraindicating factors.
✕Probably not a fit
Patients without access to a smartphone, without a Zalo account, or with conditions preventing follow-up testing may derive little or no benefit.

What this trial studies
This randomized trial evaluates whether sending reminder and guidance via a chat app improves adherence to follow-up testing after AI-interpreted chest X-ray abnormalities. Participants are adults aged 40–62 at risk for lung disease, working, and owning a Zalo account, recruited at Nhan Dan Gia Dinh Hospital in Ho Chi Minh City. The study compares standard care to an intervention using the Zalo app to facilitate communication and scheduling for follow-up imaging or tests. The trial aims to quantify differences in follow-up compliance between groups and to characterize barriers to adherence in this setting.
Why it matters
Potential benefit: If successful, patients may have higher rates of timely follow-up testing, enabling earlier detection and treatment.
How similar studies have gone: Prior studies in digital health show mixed results; this approach is relatively novel in this specific setting and population.

Inclusion Criteria: * Individuals aged 40 to 62 years old and are still working * In risk population, which means they exposure at least 2 risk factors of lung cancer, following: * smoking * expose second-hand smoke * expose air pollution, bio-mass fuels * expose arsenic * expose radon * expose asbestos * having chronic pulmonary illness * having HIV * have family member's history of lung cancer (relatives within 3 generations) * Have mobile phone registered Zalo account Exclusion Criteria: * Individual smoked or had history of smoking more than 30 packs per year because they will be advised to do low dose CT scan. That is based on the guideline from Vietnam Misnitry of Health101 * Pregnant woman. It is for safety reason because research team will recommend the (+) cases or (-) cases with symptoms do LDCT or CT scan for lung cancer, that can affect the pregnancy. Therefore, if they are pregnant, research team will invite them to meet obstetricians. * History of lung cancer or TB * Who have problem in mental health is diagnosed by doctor.
